Product Features
1. Excellent non-clog performance: The large-channel impeller smoothly passes fibrous impurities up to 5 times the pump diameter and solid particles up to 50% of the pump diameter, effectively preventing winding and blockage.
2. High efficiency and stable operation: Adopting advanced and mature hydraulic design, the dynamically and statically balanced impeller and optimized volute ensure vibration-free operation and high energy efficiency. Full-head operation avoids motor overload.
3. Super durability and corrosion resistance: Chrome-plated pump shaft improves wear and corrosion resistance. Hard tungsten carbide double-series mechanical seal enables continuous safe operation for more than 8000 hours.
4. Reliable waterproof performance: The integrated vulcanized rubber sleeve at the cable-motor connection ensures long-term and stable waterproof sealing.
5. Multi safety protection: Built-in oil-water probe monitors seal damage and water ingress. Optional automatic control cabinet provides real-time protection against water leakage, overload and overtemperature faults.
6. Flexible installation and low cost: Compact structure, easy movement and installation. No pump room required, greatly reducing project cost. Two installation modes are available: fixed automatic coupling and mobile free installation.
7. Low maintenance & unattended operation: Double-rail automatic coupling system facilitates maintenance without entering the sewage sump. Float switch realizes automatic start-stop according to liquid level changes.
8. Dry-run resistance: Optional jacket external circulation cooling system ensures safe operation under dry running conditions.
